o adjoint: |
| 8 |
|
bug fix spotted by Gael Forget: |
| 9 |
|
seaice_advection and thsice_advection still had |
| 10 |
|
legacy CPP options to avoid CS corner updates for adjoint |
| 11 |
|
o pkg/seaice: |
| 12 |
|
=> Change some of the defaults (2011/05/29): |
| 13 |
|
- change SEAICEuseFluxForm default (from False to True) |
| 14 |
|
- change DIFF1 default (from 0.004 m/s to 0. m/s) |
| 15 |
|
And print warnings if DIFF1 is not set in data.seaice and centered |
| 16 |
|
avection scheme is used without any diffusion. |
| 17 |
|
also: |
| 18 |
|
- fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F; |
| 19 |
|
- set SEAICEdiffKh[] default in the same way as SEAICEadvSch[] |
| 20 |
|
- stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any |
| 21 |
|
other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with |
| 22 |
|
#undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE. |
| 23 |
|
update results of test exp.: |
| 24 |
|
lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20) |
| 25 |
|
output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200) |
| 26 |
|
output_adm.noseaicedyn (SEAICEuseFluxForm=T) |
| 27 |
|
offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T) |
| 28 |
|
seaice_obcs: output (SEAICEuseFluxForm=T) |
| 29 |
|
and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004) |
| 30 |
|
for standard fwd & AD lab_sea tests (to keep the same output). |
| 31 |
|
o pkg/seaice/seaice_growth.F: |
| 32 |
|
- use Ian Fenty's capping formulas for actual ice |
| 33 |
|
thickness thoughout EVOLUTION branch. |
| 34 |
|
- put treatment pathological case #2) in CPP brackets |
| 35 |
|
(ALLOW_AVOID_INFINITESIMAL_AREA, undef by default). |
| 36 |
|
- update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly. |
| 37 |
|
o pkg/seaice: |
| 38 |
|
- seaice_diffusion.F : remove the min(DX,DY) factor permanently; |
| 39 |
|
pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter; |
| 40 |
|
also pass fac as a param, which can be 1. (to update the tendency |
| 41 |
|
field) or the time step (to update the field itself). |
| 42 |
|
- seaice_advdiff.F: for multidim, call seaice_diffusion with |
| 43 |
|
e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call |
| 44 |
|
seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step. |
| 45 |
|
- SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F : |
| 46 |
|
hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc. |
| 47 |
o pkg/seaice: |
o pkg/seaice: |
| 48 |
diffusion with centered advection scheme (diffus.F & advect.F): |
diffusion with centered advection scheme (diffus.F & advect.F): |
| 49 |
- simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside) |
- simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside) |
